I'm setting up Conditional Access. We want it setup to prompt for MFA on all websites when you aren't in a trusted location, (we have this setup), and bypass MFA when you are in a trusted location.
We have a specific website that we want to always prompt for MFA no matter the location that you are in. But I can't seem to find the correct set of settings to make this happen. What settings do I need to use (as well as what settings to I need to use for a new app registration) to make this work? This is a 3rd party website that I don't control, but the data on it is very sensitive, so we want to have MFA on it at all times.
